The only place you definitely need PPF is in front of the rear wheel arches, the front tyres kick up tiny road grit that peppers the lower area just in front of the rear wheels.
My car is Night Blue Metalic, you can’t see the damage but you can feel it when polishing the car.
I got a local PPF installer to fit two shark fin shaped panels in front of the rear wheel arches, took him 20 minutes, charged me £40, problem solved.
Porsche should fit PPF in this area at the Factory or the dealer should tell you about the problem before you start driving, so you can prevent any damage.
I’ve done just over 5000 miles now and only have one tiny stone chip on the lower bonnet that I’ve touched up myself with a paint stick from Porsche.
Basically just don’t follow closely to the car in front to avoid stone chips.
